In today's Self-Fulfilling Prophesy news, researchers have found that men who don't need Viagra but take it anyway because they like how hard it makes their penises are dooming themselves to a future of self-doubt and the sexual floundering that comes with underconfidence. I guess in that way, recreational Viagra abuse is sort of the pharmaceutical equivalent of a WaterBra.

According to urologists, there's no evidence linking long term use of Viagra for any reason in a physical or chemical or hormonal decline in a man's ability to get a boner (or, if you want to use proper medical terminology, "stiffy," "hard on," or "dong ding"). But that doesn't mean that using Viagra or other erectile dysfunction drugs don't have potentially bad effects for people who dabble without dick problems.

The problem with boarding the V train before it's time is not a physical one, but a mental one. Men who use ED drugs risk getting themselves used to the sort of pocket bananas generated by chemicals and not the good, old fashioned organic ones they can make themselves, from scratch. As a result, they become less confident in their ability to achieve* erection themselves, without the aid of chemicals. And their nervous state translates to less confident erections, which translates to their wives or girlfriends or boyfriends or mistresses or rent boys telling them that it's okay because it happens to lots of guys and let's just finish watching The Daily Show and go to sleep, honey, okay?

Nonessential ED drug use can also mask a man's natural decline in dick functionality (another medical term), and men who quit after a prolonged reliance on the drugs may be unpleasantly surprised by their diminishing prowess, which, again, leads to underconfidence, which leads to awkward makeout sessions followed by soft crying.

Yet another reason not to abuse prescription drugs.

* I love how erections are positioned as something that can be "achieved," like getting your Master's Degree or bench pressing 100 pounds. "My many achievements include thousands of erections," say no one's résumés.
